Hello,
Could you clarify how Pgpool works with connections. Our Java
application has its own Hikari connection pool to connect to the
database. By default, the minimum and maximum number of pools in Hikari
CP is 10.
When connecting to PostgreSQL via Pgpool, the application establishes 10
connections to the database at once. Further, on subsequent connections
from application, the established connections are not used, but new ones
are created. On PostgreSQL, the number of connections with the
application is growing - 12, 15, 20 and more.
However, when the application works with PostgreSQL directly without
Pgpool, the number of connections in the database remains 10. I would
like to know the mechanism for managing connections in Pgpool.
Could you tell me about this or point out me please where I can read
about it.
Thanks in advance.
